Henri Charles Arnauld de Pomponne

Abbot Henri Charles Arnauld de Pomponne (1669, The Hague[1] – 1756) was a French ecclesiastic and diplomat.

He was the third son of Simon Arnauld de Pomponne, Secretary of State for Foreign Affairs, and was born at La Haye (The Hague), where his father was ambassador.

Commendatory abbot to the royal abbey of Saint-Médard at Soissons and at Saint-Maixent, king's almoner, and conseiller d'État, he was chancellor and Garde des Sceaux of the Ordre du Saint-Esprit from 1716 to 1756.

Brother in law of Torcy, then Secretary of State for Foreign Affairs, abbot de Pomponne was made French ambassador to the Republic of Venice during the War of the Spanish Succession.

He managed to seize the papers of a secretary to a Piedmont-Savoy diplomat, which were published in Switzerland to expose the plots of Louis XIV's enemies.
